Lithium-Ion Battery Storage Could Aid Grid

Usually when we mention lithium-ion batteries here at EarthTechling, it’s when referencing the power system of an electric vehicle or plug-in hybrid. Earlier this month, however, telecommunications company and computer manufacturer NEC released a new home energy management system using the battery technology for home in Japan, which is enduring mandatory power cuts this summer in the wake of the devastating March 11 earthquake and tsunami.

NEC’s battery system connects to a home’s distribution panel, and can coordinate power supply with the utility, storing power during the night, when power use droops, while providing power to the home when demand on the grid is high.

According to NEC, the device itself, along with the interactive software reporting seen in the photo above, will work with solar power systems as well, a clean energy source more and more homeowners could start to embrace in light of the recent nuclear contamination problem following the disaster.

Currently, the home energy management product is only available to construction companies and businesses in Japan, but NEC is planning to expand its reach into the energy storage market in 2012, potentially opening up individual purchasing in the near future.
